Safety Information
Electrical safety
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
Make sure that your power supply is set to the correct voltage in your area. If you are not
sure about the voltage of the electrical outlet you are using, contact your local power
company.
If the power supply is broken, do not try to fix it by yourself. Contact a qualified service
technician or your retailer.
Operation safety
Before installing the motherboard and adding devices on it, carefully read all the manuals
that came with the package.
Before using the product, make sure all cables are correctly connected and the power
cables are not damaged. If you detect any damage, contact your dealer immediately.
To avoid short circuits, keep paper clips, screws, and staples away from connectors,
slots, sockets and circuitry.
Avoid dust, humidity, and temperature extremes. Do not place the product in any area
where it may become wet.
Place the product on a stable surface.

Chapter 1 - Product Introduction
1.1 Before you Proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
Unplug the power cord from the wall socket before touching any
component.
Use a grounded wrist strap or touch a safely grounded object or a
metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity
Hold components by the edges to avoid touching the ICs on
them.
Whenever you uninstall any component, place it on a grounded
anti-static pad or in the bag that came with the component.
Before you install or remove any component, ensure that the ATX
power supply is switched off or the power cord is detached from
the power supply. Failure to do so may cause severe damage to
the motherboard, peripherals, and/or components.
1.2 Motherboard Overview
Before you install the motherboard, study the configuration of your chassis to ensure that the
motherboard fits into it. Refer to the chassis documentation before installing the motherboard.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and
damage motherboard components.
1.2.1 Placement Direction
When installing the motherboard, make sure that you place it into the chassis in the correct
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
1.2.2 Screw Holes
Place eight (8) screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over tighten the screws! Doing so can damage the
motherboard.

1.3 System Memory
1.3.1 Overview
The motherboard comes with two Double Data Rate 4 (DDR4) Small outline Dual Inline
Memory Modules (SODIMM) sockets.
DDR4 SDRAM, an abbreviation for double data rate fourth generation synchronous dynamic
random-access memory, is a type of synchronous dynamic random-access memory (SDRAM)
with a high bandwidth ("double data rate") interface. The primary advantages of DDR4 over
its predecessor, DDR3, include higher module density and lower voltage requirements,
coupled with higher data rate transfer speeds.
DDR4 SODIMM sockets

1.3.2 Installing a DIMM
Make sure to unplug the power supply before adding or removing
DIMMs or other system components. Failure to do so may cause
severe damage to both the motherboard and the components.
1. Locate the SODIMM socket on the board.
2. Hold two edges of the SODIMM module carefully, and keep away of touching its
connectors.
3. Align the notch key on the module with the rib on the slot.
4. Firmly press the modules into the socket which will automatically snap into the mounting
notch. Do not force the SODIMM module in with extra force as the DIMM module only fits
in one direction.
5. Press down until SODIMM module Mounting Notch clicks in.
A DDR4 SODIMM is keyed with a notch so that it fits in only one
direction. DO NOT force a SODIMM into a socket to avoid
damaging the DIMM. 
The DDR4 SODIMM sockets do not support DDR3 SODIMMs.
DO NOT install DDR3 SODIMMs to the DDR4 SODIMM socket.

1.3.3 Removing a DDR4 DIMM
1. Press the two ejector tabs on the slot outward simultaneously, and then pull out the
DIMM module.
Support the DIMM lightly with your fingers when pressing the ejector
tabs. The DIMM might get damaged when it flips out with extra force.
